key markings such as those on emergency switches must not be allowed to fade. To achieve this, colourants with particularly high
temperature stability are required to ensure that the component retains its colour and function even under thermal stress. To date, however, there has been very limited scope for adjusting colours for such components, as only inorganic colourants have been sufficiently temperature-stable to be used in these applications.. Rowa Masterbatch can produce brilliant colours, such as RAL 1021 Colza yellow, RAL 2010 Signal orange, RAL 3000 Flame red, RAL 4006 Traffic purple, RAL 5015 Sky blue or RAL 6018 Yellow green, tailor-made for high-temperature applica- tions. The colourants selected are colour-stable at processing temperatures up to 380°C and are said to exhibit very good coverage even with thin wall sections. Mechanical properties of glass fibre-rein- forced compounds are mostly retained. Each year Gabriel-Chemie shows off the latest developments and market trends by launching a new Colour Vision collection. The latest edition, which came out at the beginning of 2021, is
New additive masterbatches from Eurotec
Eurotec has recently extended its product line with MasterTec additive masterbatches in 20 different polymer categories. They include masterbatches containing antimicrobials, UV stabilisers, heat stabilisers, special additives that improve the filtration of surgical masks, flame retardants, antistatic and electrically conductive additives, additives that enable plastics particles to be detected by metal detectors in food packaging lines, mould-release agents, and additives that reduce the friction coefficient of materials and enhance scratch and abrasion resistance.

characterised by a “multitude of optical and haptic special effects in a combination of marbling and laser marking [to create special haptic effects] as well as unique effect and natural colours,” the company says. Gabriel-Chemie has its own laser marking technology.
Gabriel-Chemie launched its first marble
products in 2017. They give each product a unique surface pattern and are an interesting way of adding value to PCR, the company says. The latest versions, called European Marble,
were launched to coincide with Euro 2020, the European football (soccer) championships that were postponed for a year and came to a climax at the beginning of July. Colour combinations represent the flags of the playing countries. Gabriel-Chemie offers, on request, near-infrared (NIR) inspection and certification of all master- batches for its customers, to guarantee detectabil- ity at the sorting stage during recycling. Martin Horvath, Corporate Product Manager at Gabriel- Chemie, says: “The detectability directly from Gabriel-Chemie promises product and quality safety that our customers can always rely on. The newly launched product mix, including COTREP [Comité Technique pour le Recyclage des Embal- lages Plastiques - Technical Committee for the Recycling of Plastic Packaging] certified products, as well as the numerous customer inquiries we have received, confirm the rapidly growing need for NIR-detectable products. “
